WRENCH.

Application filed June 14, 1913.

To all whom it may concern Be it known that we, CHARLES A. BROOK- MAN and TrioMAs D. Connor, citizens of the United States of America, and residents of Jolley, Calhoun county, Iowa, have invented a new and useful Wrench, of which the following is a specification.

The object of this invention is to provide an improved construction for a handleoperated monkey wrench.

A further object of this invention is to obtain convenience and increased power in operation of a screw-operated wrench.

A further object of this invention is to provide an improved construction for a combined pipe and monkey wrench.

Uur invention consists in the construe tion, arrangement and combination of elements hereinafter set forth, pointed out in our claims and illustrated by the accompanying drawings, in which Figure 1 is a longitudinal section of one form of our improved wrench. Fig. 2 is a face elevation. of the same. Fig. 3 is a side elevation illustrating the embodiment of our improved construction in a combined pipe and monkey wrench.

In the construction of the device as shown the numeral 10 designates a stationary jaw, which jaw is formed with an integral shank 11, angular in cross-section. The shank 11 is formed with a continuation comprising a rounded spindle 12. The shank 11 and spindle 12 are formed with a continuous, forwardly opening groove 13, extending from near the upper end of said shank to the end of said spindle. An adjustable or movable j aw 14c is slidingly mounted on the shank 11 and is formed with an integral block 15 projecting within and slidable longitudinally of the groove 13, and said block is formed with a threaded bore. The spindle 12 is threaded adjacent its conjunction with the shank 11 and a collar 16 is adapted to be screwed thereon, abut the lower end of said shank, and limit movement of the jaw ll in one direction. A handle member 17, of tubular form, which may be of wood or milled iron, is mounted looselv on the spindle 12 below the collar 16. The spindle 12 is threaded eXteriorly at its extremity and a collar 18, of less diameter than the collar 16 and handle 17 is screwed thereon and holds said handle in place. The handle member 17 in reduced at its lower end and.

is exteriorly threaded, and a cap 19 is screwed thereon over the collar 18. The collar 16, handle 17 and cap 19 preferably are of uniform diameter and together form a continuous handle for the wrench. A rod 20 is fixed at one end within and to the cap 19 and extends through said cap, the collar 18, handle member 17, collar 16, within the groove 13 of the spindle and shank. The rod 20 is formed with a screw 21 (preferably left-handed) in its upper end portion, and said screw is seated in the block 15 of the movable jaw member. Independent rotary movement of the handle member 17 and cap 19, or the cap 19 alone, resulting in a rotation of the rod 20 and screw 21, causes the jaw member id to move toward or away from the jaw member 10. Thus the wrench may be operated from the very tip of the handle, and may be operated when in confined or restricted spaces. When convenient to grasp the entire handle in his hand, the operator may secure much increased power for the operation.

In the construction according to Fig. 3, the jaws 10 14* are extended on both sides of the shank 11, and one pair of said double jaws are formed with serrations or teeth 22 on their engaging faces, adapted especially for the gripping of pipe in a common manner. Thus a combined pipe and monkey wrench is produced, and the other elements of construction are identical with those hereinbefore described. A set screw 23 may be mounted through the collar 16 and hold the same in position, if deemed necessary. Any suitable means may be provided for securing the cap 19 to the handle 17 if desired.

We claim as our invention- 1. A wrench, comprising a stationary jaw member, a shank thereon formed with a forwardly opening longitudinal groove, an adjustable jaw member slidingly mounted on said shank and formed with a block entering said groove, a collar screwed on said shank and limiting movement of said adjustable jaw member in one direction, a handle rotatively mounted on said shank, a collar screwed on the end of said shank against said handle, a cap screwed on said handle over said latter collar, and screw connections between said cap and the block of said movable jaw member.

2 A. wrench, comprising a stationary jaw member, a shank thereon formed with a forwardly opening longitudinal groove, an adjustablejaw member slidingly mounted on said shank and formed with a block entering said groove, said shank terminating in arounded spindle, a collar screwed on said spindle and abutting said shank, a handle rotatively mounted on said spindle, a collar screwed on the end of said spindle and abut ting said handle, a cap screwed on the lower end of said handle over the latter collar,
